Works on HVDC DolWin 5 in progress

News | January 19, 2023

In January, our teams in Germany continued the implementation of works in the framework of the HVDC interconnection DolWin 5 construction.

The focus of Elnos Group works rests on a converter station Emden in Germany, with 900 MW of installed power and +/- 320 kV DC voltage level, with a subcontractor the company Hitachi Energy, we are performing overall electrical assembly work.

This is the first time we have performed work at a converter station in the highly demanding German market. The equipment being installed in these stations is significantly larger and much more complex and sensitive compared to the equipment used in conventional AC station.

Our teams at the site are currently carrying out the demanding assembly of large coils weighing 6.5 tons, which is a phase that was preceded by detailed preparations.

We will soon begin the implementation of the phase of laying MV and LV cables, during which our teams will lay about 82 kilometers of cables.

Three teams of our company are currently working on the construction site. The number of active workers is constantly increasing and by the end of the month, more than 30 of them will be working here.

Our part of the works on construction of this converter station is to perform overall electrical assembly works that include installation of all equipment necessary for its operation, protection and control cabinets, cable trays, and control and monitoring system. The works also include laying and connection of MV and LV cables, measurement cables, and control and signal cables as well as equipment testing and partial support during commissioning.
